What is the importance of comparing wild type and mutant fruit flies in genetic research?

Answers

Answer 1

Answer: Wild-type and mutant fruit flies are important in genetic research as it gives the chance to know the organization of the wild sort quality or protein in order to know the thinking behind elements that cause certain attributes. What's more, wild-sort mutants are utilized as a control in hereditary research tests.

Certain chest deformities prevent normal expansion of the chest. Explain why this makes ventilation difficult in terms of pressure and volume.

Answers

The lungs work by expanding and going back to their original size when you inhale and exhale. The rib cage also expands so the lungs can have more air inside and expand. Due to deformities, the rib cage might not expand and/or the diaphragm might not lower itself, which might lead to pressuring the lungs not to expand and having a lower volume of air inside. This leads to breathing difficulties.

Messenger RNA carries a(n) ___________ of the DNA’s instructions out of the nucleus to the ___________.a. exact copy; ribosome
b. transcript; ribosome
c. exact copy; mitochondria
d. transcript; mitochondria

Answers

b. transcript; ribosome

Ribosomes are one of the most important organelles in the cell, mostly part of the rough endoplasmic reticulum. It manufactures enzymes such as proteins which will be utilized by many organelles in the cell. Microtubules are one, responsible for the framework and acts as a skeleton of the cell –cytoskeleton needs proteins, also cytoplasm and other organelles of the cell. For a prokaryote or a eukaryote cell to survive, they need protein.

What roles do polysaccharides play in living things?

Answers

Polysaccharides play crucial roles in living things due to their diverse functions and properties. As complex carbohydrates made up of multiple sugar units, they serve as important sources of energy and structural components in organisms.

1. **Energy Storage:** One primary role of polysaccharides is to store energy for short-term and long-term use. Plants store excess glucose in the form of starch, while animals store it as glycogen in the liver and muscles.

2. **Structural Support:** Polysaccharides provide structural support in cell walls of plants, algae, and some bacteria. For example, cellulose forms the rigid cell walls of plant cells, giving them shape and support.

3. **Protection and Lubrication:** Some polysaccharides, like chitin found in the exoskeletons of insects and crustaceans, provide protection and structural support. Hyaluronic acid, a polysaccharide in connective tissues, acts as a lubricant and shock absorber.

4. **Cell Recognition:** Polysaccharides are also involved in cell recognition and signaling processes. They form part of cell surface markers and play essential roles in immune responses and cell communication.

Overall, polysaccharides are essential biomolecules that fulfill diverse functions, contributing to the proper functioning and structure of living organisms.
